1. Problem Description

The problem asks us to find which of the given binomials is a factor of the polynomial x36x2+11x6x^3 - 6x^2 + 11x - 6.

2. Solution Steps

We can use the Factor Theorem to check each binomial. The Factor Theorem states that a polynomial f(x)f(x) has a factor (xa)(x-a) if and only if f(a)=0f(a) = 0.
a) Check if x1x-1 is a factor.
Let x1=0x-1 = 0, so x=1x = 1.
Then we substitute x=1x = 1 into the polynomial x36x2+11x6x^3 - 6x^2 + 11x - 6:
f(1)=(1)36(1)2+11(1)6=16+116=1212=0f(1) = (1)^3 - 6(1)^2 + 11(1) - 6 = 1 - 6 + 11 - 6 = 12 - 12 = 0.
Since f(1)=0f(1) = 0, then x1x-1 is a factor of x36x2+11x6x^3 - 6x^2 + 11x - 6.
b) Check if 2x+32x+3 is a factor.
Let 2x+3=02x+3 = 0, so x=32x = -\frac{3}{2}.
Then we substitute x=32x = -\frac{3}{2} into the polynomial x36x2+11x6x^3 - 6x^2 + 11x - 6:
f(32)=(32)36(32)2+11(32)6=2786(94)3326=2785443326=27810881328488=27108132488=31580f(-\frac{3}{2}) = (-\frac{3}{2})^3 - 6(-\frac{3}{2})^2 + 11(-\frac{3}{2}) - 6 = -\frac{27}{8} - 6(\frac{9}{4}) - \frac{33}{2} - 6 = -\frac{27}{8} - \frac{54}{4} - \frac{33}{2} - 6 = -\frac{27}{8} - \frac{108}{8} - \frac{132}{8} - \frac{48}{8} = \frac{-27 - 108 - 132 - 48}{8} = \frac{-315}{8} \neq 0.
So 2x+32x+3 is not a factor.
c) Check if x+7x+7 is a factor.
Let x+7=0x+7 = 0, so x=7x = -7.
Then we substitute x=7x = -7 into the polynomial x36x2+11x6x^3 - 6x^2 + 11x - 6:
f(7)=(7)36(7)2+11(7)6=3436(49)776=343294776=7200f(-7) = (-7)^3 - 6(-7)^2 + 11(-7) - 6 = -343 - 6(49) - 77 - 6 = -343 - 294 - 77 - 6 = -720 \neq 0.
So x+7x+7 is not a factor.
d) Check if x+1x+1 is a factor.
Let x+1=0x+1 = 0, so x=1x = -1.
Then we substitute x=1x = -1 into the polynomial x36x2+11x6x^3 - 6x^2 + 11x - 6:
f(1)=(1)36(1)2+11(1)6=16116=240f(-1) = (-1)^3 - 6(-1)^2 + 11(-1) - 6 = -1 - 6 - 11 - 6 = -24 \neq 0.
So x+1x+1 is not a factor.
Since f(1)=0f(1) = 0, x1x-1 is a factor.
